FRESNO, Calif. — A California man was arrested Wednesday on suspicion of sending hoax letters labeled “anthrax” to scores of media outlets, the FBI said Wednesday, warning that many of the threats may still be in the mail.
Marc M. Keyser, 66, sent more than 120 envelopes containing a compact disc that had a packet of sugar labeled “Anthrax Sample” along with a biohazard symbol, the FBI said in a news release. The CD was titled “Anthrax: Shock & Awe Terror.”
Keyser was taken into custody at his home in Sacramento, the FBI said. At least some of the packages had Keyser’s return address on them, said FBI agent Steve Dupre.
None of the packets has so far tested positive for hazardous material, the agency said. Authorities did not say what was on the CD.
More mailings will probably be received over the next few days; recipients should contact their local FBI office, Dupre said.
Letters have been received by The Atlantic magazine, The Charlotte (N.C.) Observer, two Sacramento television stations, the San Diego Union- Tribune and the office of Republican Rep. George Radan ovich in Modesto. A McDon ald’s restaurant in Sacramento also received a package.
